MACHINE FOR WINDING BOBBINS.

SPECIFICATION forming part of Letters Patent No. 436,521, dated September 16, 1890. Application filed November 6, 1889. Serial No. 32%8601 (No model.)

To all whom it may concern:

Be it known that I, J OHN W. FOSTER, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Machines for Winding Bobbins, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representinglike parts.

This invention is an improvement on that contained in United States Patent N 0. 404,831, granted to me June 11, 1889, to which reference may be had.

In the patent referred to the spool on which the yarn is wound rests on a drum interposed between the said spool and a rotating driving-cylinder, the said drum taking up considerable space, and to arrest the rotation of the spool when full or in case the yarn breaks the said drum is lifted automatically by devices also requiring considerable space.

In my efiorts to improve and simplify the construction of the machine described in the said patent, and at the same time reduce its cost of manufacture and the power required to run it, I have discovered that I may dispense with the solid drums referred to and accomplish the purpose effected by the drums by the employment of a thin metallic hollow shell surrounding the said driving-cylinder and actuated by it to rotate the spool or other device resting thereon and on which the yarn I is to be wound.

In accordance with my invention the hollow shell surrounding the said cylinder and having an internal diameter a little greater than the external diameter of the driving-cylinder is rotated by the said driving-cylinder so long as the said shell rests upon-the said cylinder; but whenever the said shell is slightly lifted, so as to place its longitudinal center coincident with the center of rotation above the rail, where they may take bearing in the spool-stands rather than in independent stands below the rails, thus enabling the said shafts and cylinders to be in plain sight and accessible.

My invention consists in the combination, with a rotating cylinder and a surrounding rigid shell adapted to be rotated thereby, of means to lift or suspend the said shell out of contact with the said cylinder when it is dcsired to stop the rotation of the said shell; also, in the combination, with stands, cheekpieces to hold a spool and permit it to be rotated in the said stands, a shaft, a cylinder thereon, and rigid shell surrounding the said cylinder and adapted to support the said spool, of means to lift or suspend the said shell from contact with the said cylinder when it is desired to stop the rotation of the said spool; also, in the combination, with a rotating cylinder, of a hollow shell surrounding it and rotated by the said cylinder by frictional contact.

Other features of my invention will be described in this specification and pointed out in the claims at the end thereof.

Figure 1, in section and elevation, shows a sufficient portion of one side of a Winding or spoolingmachine with myimprovement added to enable my invention to be understood.

Fig. 2 is a partial section in the line a", Fig. 1, the shell and cylinder being in driving contact; Fig. 3, a similar section, showing the shell and cylinderout of driving contact; and Fig. at is a detail of part of the stop-motion devices.

The frame-work consists of suitable end I pieces A (but one shown) and suitable rails or girts A A A The rails A A are arranged in pairs; but, as the parts to be carried by them are just alike, I shall only illustrate said parts on the rails A The rails A have bolted to them stands a b, arranged in pairs, the upper slotted ends of which receive the end journals of a suitable shaft or of cheekpieces 0 c on or between which to hold the spool or device d on which the yarn is to be wound. The upper part of the stand b is adapted to be turned over, together with its cheek-piece, when it is desired to remove or apply a spool.

The cylinder e is herein shown as composed of two annular disks fixed to a shaft 6'; but instead the said cylinder may be in one piece as long as the barrel of the spool, it, when made in two short sections, as shown, being lighter. The shaft e, taking its bearings in the stands a b, has a pulley 6 about which is placed a belt 6 surrounding a pulley c on the main shaft 6 which maybe rotated in any usual way.

The spring f, connected to the upper and lower ends of the stand I), aids in keeping the upper part of the stand either in its upright position or turned over about the hinge 2.

The girt A has two uprights g g, in which rests the slide g, having pivoted on it the stop-motion latch 9 beneath which on said slide are the two stops 3 1, the slide being surrounded by a spring g normally to push the same to the right in Fig. 1.

' The rotating ratchet-shaft 34. has a ratchetwheel 33, one for each cylinder, so that whenever a drop-wire (not shown,but of any suitable construction) drops on the outer or lefthand end of the latch g (see Fig. 1,) which happens whenever a yarn breaks, it lifts the inner or right-hand end of the said latch, so that the ratchet-wheel strikes the latch and pushes the slide g to the left,.viewing Fig. 1, to thereby effect the stopping of any spool.

The parts so far described, with the exception of the cylinder, composed, as shown, of two disks, and the particular shape of the inner end of the slide g, to be further described, and the location of the shaft 6 are all substantially as in the said patent. The cylinder 6 on the shaft e is surrounded by a hollow shell h, preferably of metal; but it may be of other rigid material. When the shell h surrounding the said cylinder, as shown, rests with its weight thereon, as in Fig. 2, the rotation of the cylinder acts to rotate the said shell, and thelatter rotates the spool or equivalent device resting thereon. The internal diameter of the shell shown is a little greater than the external diameter of the cylinder 6, and the length of the shell is sufficient to extend from one to the other head of the spool, and the shape of the cylinder is such as to support the shell near each end. The rockshaft 7, directly under and parallel with the shaft e and resting in bearings 16, has attached to it a lever 8 and arms 6 and 13.

The lever 8 has a weight 10 or equivalent by which normally to turn the said rock-shaft from the position of Fig. 2 into the position of Fig. 3 whenever the slide g is moved to the left far enough to remove the shoulder 5 from the arm 6, the arm 13 at such time preferably meeting the girt A and the arm 6 the finger 12 of the slide g. When the slide g is moved to the left, as described, to thus release the said rock-shaft 7, the lifting device or supportm (shown as pivoted at 17 on an arm 18 preferably a part of the lever 8) is moved from the position shown in Fig. 2 to that shown in Fig. 3, and, viewing Fig. 3, it will be seen that the shell h is lifted far enough to remove its interior from contact with the cylinder e, and as a result thereof the said shell is supported by the lifting device, the longitudinal center of the shell being then substantially coincident with the center of rotation of the cylinder or of the shaft e, at which time the rotation of the shell and whatever rests on it is stopped.

For sake of lightness I have shown the cylinder 6 composed of two wheels or disks; but I may employ one Wheel or roll as long as the shell or the barrel of the bobbin.

When the slide g is moved to the left and the arm 6 is stopped against the finger 12, the said arm, by acting against the shoulder 20, keeps the slide g out, and the shell remains elevated or suspended and at rest.

Then it is desired to drop the shell and start it in rotation, the operator, by engaging the handle at, fast on the rock-shaft 7, turns the said rock-shaft in a direction to lower the lifting device or support on and let the shell rest on the roll a, such movement of the rockshaft lifting the weight and removing the arm 6 from the shoulder 20, so that the spring 9 acts to push the slide to the right and again place the shoulder 5 in place to hold the arm (5 and keep the weight lifted.

Believing myself to be the first to surround loosely a cylinder or roll bya cylindrical metallic or rigid shell which is adapted to be rotated by contact with the said cylinder, but which shell may remain at rest when it is removed from contact with the said cylinder, I do not desire to limit my invention to the exact form of devices shown by which to effect the lifting of the said shell, nor do I desire to limit my invention to the exact thing shown which is to be rotated by surface contact with the said shell.

It will be understood that an operative machine for winding will contain a number of cylinders and shells, they being duplicated along one or the patent referredto. Soherein I have deemed it unnecessary to show but one cylinder, shell, and spool, and at one side of the frame, the shaft 6 being broken off, the said shaft in practice having at its right-hand end a cylinder such as shown at its left-hand end.

Any usual or suitable traverse-motionsuch, for instance, as shown in the said patefit-may be employed to guide the yarn onto the spool.

1. The combination, with a rotating cylinder and a surrounding rigid shell, of means to lift or suspend the said shell out of contact from the said cylinder when it is desired to stop the rotation of the said shell, substantially as described.

2. The stands, the cheek-pieces to hold a spool, the shaft e, a cylinder thereon, and the shell h, surrounding the said cylinder, combined with means to lift or suspend the said shell, substantially as described.

3. The stands, the cheek-pieces to hold a both sides of the machine, as in.

spool, the shaft e, a cylinder thereon, and the shell h, surrounding the said cylinder, combined with means to lift or suspend the said shell and with the stop-m otion slide and means to move it to enable the lifting device to act and lift the shell, substantially as described.

4. The rotating cylinder, combined With the hollow shell surrounding the said cylinder loosely and driving it by the contact of the cylinder with the inner wall of the said shell, 10 substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
